چکیده
Abstract This letter proposes a novel wave-transparent and decoupling antenna in broadband dual-Polarized dual-Band shared-aperture array. It is implemented by kneading the double-arrow-stripe-shaped structure into frequency-selective metasurface of lower-frequency-band (LFB) arms. The LFB radiator can be considered as array-decoupling for higher-frequency-band (HFB) antennas placed below. system consists 2 × HFB (3.3-3.6 GHz)arrays an (1.65-2.58 GHz) with decoupled (WTDS). Then, without adding additional structure, in-band isolations co- cross-polarized between are promoted to >25.6 dB >25 only relying on form itself.

Shared-Aperture Multi-Band Dual-Polarized SAR Microstrip Array Design
Since the 1970s, the remote sensing synthetic aperture radar (SAR) systems have been devel‐ oping increasingly. The SIR-C/X SAR mounted on the American Space Shuttle Endeavour firstly completed the high resolution 3D imaging all over the globe in Feb. 2000 [1]. It employs three dual-polarized sub-arrays operating at L-, Cand X-bands, respectively, as shown in Fig. 1[2]. The multi-band dual-pola...

This paper presents air gap aperture coupled microstrip antenna for dual-band operation over the frequency range of (2.9 to 6.0 GHz). This antenna differs from any other microstrip antenna with their feeding structure of the radiating patch element. Input signal couples to the radiating patch trough the aperture that exists on the ground plane of microstrip feed line. The dual-band achieved by ...
